Thread: An updated guide to enable JCV, Highway Mode, Lane assist & TTS on 2x5w

Hello: I recently stumbled across this thread. I have a nuvi 265W. I am conisdering trying this. These instructions were from 2 years ago. Currently, my 265W (US version) has FW 7.5. Does this method still work? If the GPS is flashed to Singapore FW, will it work with current US Map and JCV? What about FW updates? What happens if I run Garmin WebUpdater on a GPS flashed to Singapore FW, will it re-install US firmware?

Hi,

I also have a nuvi 205W from USA - FW 7.5, HWID 1091, S4. Will this method work for it? Also, it seems these updates will remove ecoroute from the device. Please advise.
Thanks.
